If you make more than that, you're being squeezed down to it. Below that wage, machines don't make sense, yet. And with the squeeze happening with all of the 'sharing' economy, your wages will go even lower.
In effect, capitalism has failed us, as a country and as a world. Do I know the answer? Nope. Some will say communism, socialism, anarchism, or some -ism. But something will need to be set up differently. Lest we will see the US come out as a 3rd world country. And I'm not entirely sure it's not a good way there.
